Infineon Technologies S70FL01GSDSBHBC10

Overview

S70FL01GSDSBHBC10 from Infineon is a 1 Gbit (128 Mbyte) dual-die SPI flash memory with Multi-I/O interface, 3.0 V core supply, uniform 256-kbyte sector erase, and support for Quad DDR read commands. It implements two stacked S25FL512S dies in a single BGA-24 package, enabling high-density nonvolatile storage for boot code and firmware in industrial and automotive systems.

For engineers reviewing the S70FL01GSDSBHBC10 datasheet, S70FL01GSDSBHBC10 pinout, S70FL01GSDSBHBC10 application, or S70FL01GSDSBHBC10 equivalent, key selection considerations include dual-die addressing via CS1#/CS2#, independent status/configuration register management per die, OTP security array, and AEC-Q100 Grade 2 qualification (−40°C to +105°C).

Technical Context

The S70FL01GSDSBHBC10 integrates two independent 512 Mbit S25FL512S dies in a single ZSA024 BGA package, each with its own CS#, status register, configuration register, and block protection logic. It supports SPI modes 0/3, DDR read, extended 32-bit addressing, and AutoBoot from preselected address.

It delivers 1.5 Mbytes/s page programming and 0.5 Mbytes/s sector erase throughput, with 100,000 program-erase cycles and 20-year data retention. VIO is RFU; I/O operates from 1.65 V to 3.6 V while core runs at 2.7–3.6 V.

FAQ

Does S70FL01GSDSBHBC10 support true single-command 1 Gbit bulk erase?

No. Due to its dual-die stack architecture, bulk erase must be issued separately to each 512 Mbit die using CS1# and CS2#. There is no single command that erases both dies simultaneously. This is explicitly documented in Section 4.4 of the datasheet and affects firmware update sequencing logic.

Can CS1# and CS2# be asserted simultaneously for parallel reads?

No. The device does not support simultaneous access to both dies. Section 4.2 states that only one die may be accessed at a time via its respective chip select. Concurrent CS1# and CS2# assertion is undefined and may result in bus contention or incorrect status reporting.

Is VIO pin functional on S70FL01GSDSBHBC10?

No. VIO is marked RFU (Reserved for Future Use) and not supported in this device. Section 7 and Table 2 confirm VIO is not connected internally; the pin is labeled VIO/RFU and must be treated as NC or tied to VSS per layout guidelines - it does not supply I/O voltage.

How is the 2048-byte OTP array accessed and protected?

The OTP array is accessed via standard SPI commands (e.g., RDSCUR, WRSR, PP) using dedicated OTP command sequences defined in the datasheet. Once programmed, bits cannot be reset. Protection is enforced by status register lock bits (SRWD, TBPROT) and the FREEZE bit, which requires power-on-reset to clear after activation.
